Objective To observe the effect of foam dressing and polyurethane gel pad in prevention of pressure ulcer for surgical patients.Methods 140 patients in neurosurgery department were randomly divided into the control group and the experimental group with 70 patients in each group.The control group received foam-rubber cushion for conventional nursing,the experimental group used foam dressing and polyurethane gel pad to prevent pressure ulcer.Instantly after the operation and 30 min later,the situation of skin pressure ulcer was recorded respectively,the maximum diameter of erythema was measured and the process was put into phases.24 hours after the operation,patients of the above two groups were visited and the situation of skin pressure ulcer was recorded.The skin pressure ulcer and the maximum diameter of erythema were compared between the two groups.Results Cases with phase Ⅰ and phase Ⅱ pressure ulcer in the experimental group were less than those of the control group at three time points,which were instantly after the operation,30 min and 24 hours later.The diameter of erythema at three time points was also less than the control group.Conclusions Foam dressing and polyurethane gel pad could effectively prevent or alleviate pressure ulcer after operation and therefore is worthy of clinical application.

OBJECTIVE:To investigate medical staff’s awareness and knowledge level on the rational use and management of antibacterials in our hospital.METHODS:A questionnaire survey was conducted on the spot among medical staff in our hospital,and the results of survey were recorded in Excel electronic form and subjected to data analysis and processing.RESU-LTS & CONCLUSION:The medical staff had a good mastering about the general knowledge about antibacterials(such as definitions,classifications and so on).However,their answers to the questions such as reasonable antibacterial drug use,bacterial resistance,safety and expertise were relatively concentrated(tended to tick the same answer).Therefore,it is advisable to develop different forms of training through different ways among hospital medical staff to enhance their knowledge level on antibacterials and strengthen their awareness of correct and rational use of antibacterials meanwhile setting related measures and management norms.

ObjectiveTo observe clinical features and identify causative genes of reticulate pigmented anomaly of the flexures in a pedigree.Methods A survey was conducted in a pedigree with reticulate pigmented anomaly of the flexures.Clinical manifestations were recorded in details for each patient in this pedigree.Tissue specimen was obtained from the proband for histopathological examination and ultrastructural observation.Mutation scanning was carried out by PCR and direct sequencing in 3 patients in the family.ResultsAll the patients in this pedigree presented with reticular pigmentation of the flexures and idiopathic guttate hypomelanosis on the abdomen and back.Histopathological and ultrastructural study revealed epidermal hyperpigmentation with an increase in melanin content in epidermal keratinocytes but no changes in the number of melanocytes.No mutation was found in the KRT5 gene in this family.ConclusionsThis is the first case report of reticulate pigmented anomaly of the flexures associated with idiopathic guttate hypomelanosis.No mutation is identified in the KRT5 gene of patients with reticulate pigmented anomaly of the flexures in this family,indicating the existence of other causative genes.

AimThe effect of herbal tongxinluo on the thrombus formation and neointimal hyperplasia of the balloon injured rabbit abdominal aorta and iliac artery was observed. Methods36 New zealand rabbits were divided randomly into 3 groups: tongxinluo group(16 rabbits); aspirin group(11 rabbits) and control group(9 rabbits). The rabbits were treated with herb tongxinluo 0.38g·kg-1 · d-1, aspirin 50mg·kg-1 · d -1 and 0.09% natrium chloride 10 ml · d-1 alternatively. The arterial injury model was made 1 week after taking the medicine and the injured segments were taken at 24 hours,1 week or 1 month after the procedure, then the samples were stained by hematoxylin and eosin. The thrombus formation and the neointimal hyperplasia of the injured arteries were observed under microscope. Results The arterial neointimal hyperplasia was seen in both abdominal aorta and iliac artery 24 hours and 7 days after the balloon injury in each group,which led to stenosis in 5%～40% of the arterial lumen, the neointimal hyperplasia was much more significant in 2 rabbits 1 month after the balloon injury. The ratio of the arteries with thrombosis in aspirin group was less than that in the other 2 groups, but the difference was not significant. The ratio of neointimal hyperplasia in tongxinluo group was significantly less than that in aspirin and control groups. Conclusion The balloon injured rabbit abdominal aorta and iliac artery appeare to be an ideal model in researching restenosis after percutaneous transluminar coronary angioplasty(PTCA) . Herbal Tongxinluo significantly inhibit the neointimal hyperplasia of the balloon injured rabbit peripheral arteries, which indicate that herbal Tongxinluo might be a promising medicine in preventing restenosis.

Fungal elicitors are a group of chemicals that can stimulate the secondary metabolite production in plants and microbial cells. After being recognized, it could enhance the expression of related genes through the signal-transduction pathway; regulate the activity of the enzyme involved in the biosynthesis of secondary metabolites. In recent years, the inducible mechanism of fungal elicitors has been studied deeply worldwide. Meanwhile, it has acquired wide concern in the area of biological industry, especially in the fermentation industry. This paper addresses the application and prospect of fungal elicitors in the secondary metabolites of plant and microbial cells.

Objective To investigate the value of RDW for predicting death risk in the patients with acute pancreatitis (AP) and its correlation with the Ret parameters.Methods A total of 164 patients with AP in the emergency surgery of Second Xiangya Hospital of Central South University from March 2015 to May 2015 were selected ,including 151 survival cases and 13 death cases , and other 175 healthy people were selected as the control group.The venous blood was collected for detecting whole blood RDW and Ret parameters by using the Sysmex XN-1000 automatic blood analyzer.The inter-group comparison was performed by Mann-Whitney U and Kruskal-Wallis H tests ;the diagnostic value of RDW for AP death risk was evaluated by receiver operating charac-teristic(ROC) curve and area under curve(AUC).Results The RDW level in the AP death group was[15.7% (14.1% -21.8% )] , which was significantly higher than that of AP survive group [13.3% (12.7% -14.5% )] ,the difference was statistically significant (Z=40.02 ,P<0.05);AUC of RDW ROC curve for diagnosing death risk was 0.835(95% CI:0.786-0.951);With the cutoff val-ue of RDW for diagnosing the AP death risk as ≥14.5% ,the sensitivity was 71.43% (95% CI:41.90% -91.60% )and specificity was 89.40% (95% CI:83.40% -93.80% );the RDW level of AP patients was positively correlated with Ret% ,IFR ,MFR and HFR(r=0.376 ,0.502 ,0.468 ,0.475 ,P<0.01) ,and was negatively correlated with LFR (r= -0.502 ,P<0.01).Conclusion The RDW level is a good indicator for early predicting AP death risk ,its elevated degree is closely correlated with Ret generation.
